JOHN E. MANAS, OF PRINCETON, NEW JERSEY.

PROPELLER-ROTATING DEVICE.

Application filed April 5, 1920.

1 0 all whom it may concern:

Be it known that 1, JOHN E. Manes, a citizen of Greece, residing atPrinceton, in the county of Mercer and State of New Jersey, haveinvented new and useful Improvements in Propeller-Rotating Devices,(Case A,) of which the following is a specification.

This invention relates to propelling means for boats and the principalobject of the invention is to provide manually operated means fordriving a propeller.

Another object of the invention is to provide means whereby theactuating means are driven by a motion somewhat similar to that used inrowing a boat.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illus trated in the accompanying drawingsand specifically pointed out in the appended claims. In describing myinvention in detail, reference will be hadto the accompanying drawingswherein like characters denote like or corresponding parts throughoutthe several views, and in which Figure 1 is a longitudinal sectionalview through a boat provided with my invention.

Fig. 2 is an end view of one of the supporting frames and its associatedparts.

Figs. 3 and 4 are detail views.

Fig. 5 is a plan view of a modification.

Fig. 6 is a section on line 6-6 of Fig. 5.

Fig. 7 is a detail view of this modification.

Referring to the drawings 1 indicates the boat, 2 the propeller shaftpassing through said boat and 3 the propeller which is connected to theprojecting end of said shaft. The other end of the shaft carries aflywheel 4. A pair of upright frames 5 are arranged in the boat and eachframe has journaled therein a shaft 6 which carries a beveled wheel 7and a sprocket wheel 8. The propeller shaft 2 is provided with a pair ofbeveled gears 9 which mesh with the gears 7. A crank shaft 10 is alsojournaled in each frame and this shaft carries a sprocket wheel 11 whichis connected with the wheel 8 by the chain 12. A horizontal bar 13 hasits ends connected with the cranks of the crank shaft and this rodcarries a number of cross bars 1e by which the rod may be reciprocatedto cause the crank shafts to rotate.

As shown the bars 14 project across the boat Specification of LettersPatent.

and each bar is adapted to be grasped by two men, one on each side ofthe rod 13. By swaying their bodies back and forth, similar to themotion used in rowing boats, the men will move the rods let back andforth and thus rotate the crank shafts. This movement of the crankshafts will be communicated to the shafts 6 by means of the chain andsprocket wheels and as these shafts 6 are geared to the propeller shaftthe propeller will be rotated to drivethe boat.

I provide means whereby the cross bars 14; may be detachably connectedwith the rod 13 so that only those bars in use may be placed inengagement with said rod. Such means may consist of holes formed in therod to receive the bars or any other desired means may be used.

In the modification shown in Figs. 5, 6 and 7 the rod 13 is moved by thebar or bars 14E which are carried by the stationary bars 15, located oneach side of the rod 13. The inner ends of the bars 14: are providedwith rounded parts 16 which engage sockets 17 formed in the rod 13 andthese rods 14 pass through openings 18 formed in the bars 15.

In this form of the invention each bar 1% is actuated by a person andthe bar is moved similarly to an car. This movement of bars will movethe rod 18 back and forth so as to rotate the cranks and thus impartmovement to the propeller. The other parts of the form shown in Figs. 5,6 and 7 are similar to the parts shown in the first form. In the secondform the action is more like the. movement used in rowing a boat. Itwill of course be understood that any numer of rods 14 may be usedaccording to the size of the boat and the number of rowers. I prefer tomake these rods detachable so that they may be laid aside when not beingused.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claims.

What I claim is 1. Propelling means for boats comprising a propellershaft, a propeller thereon, upright frames in the boat, a stub shaftjournaled in the lower part of each frame, gears connecting each shaftwith the propeller shaft, a crank shaft journaled in the upper part ofeach frame, means for driving the stub shafts from said crank shafts, alongitudinally extending rod connected with the cranks of the crankshafts, and handles engaging parts of said rod for reciprocating therod.

2. Propelling means for boats comprising a propeller shaft, a propellerthereon, upright frames in said boat, a stub shaft journaled in thelower part of each frame, gears connecting said shafts with thepropeller shaft, a crank shaft journaled in the upper part of eachframe, sprockets and chains connecting said crank shaft with the stubshafts, a longitudinally extending rod connected with the cranks of thecrank shafts, said rod having sockets therein, supporting bars arrangedadjacent the longitudinal rod and having openings therein and handlespassing through said openings and having their ends engaging the socketsin the longitudinally extending rod.

In testimony whereof I affix my signature.

JOHN E. MANAS.
